Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bushing processing, and particularly relates to a fixing hoop for combined processing of semi-circular workpieces. Background Art
[0002] Self-lubricating bearings are divided into composite material self-lubricating bearings, solid-inlaid self-lubricating bearings, bimetallic material self-lubricating bearings, and special material self-lubricating bearings. Different self-lubricating bearings are selected according to different uses and working conditions. Among them, the solid-inlaid self-lubricating bearings have the characteristics of high load-bearing capacity, impact resistance, high temperature resistance, and strong self-lubricating ability. They are particularly suitable for occasions where lubrication is difficult and oil film formation is difficult, such as heavy load, low speed, reciprocating or swinging, and are not afraid of water flushing and erosion and scouring by other acid solutions.
[0003] During the processing of bearing bushings, since surface machining of oil injection grooves needs to be carried out on the inner wall, bushings with smaller specifications can be directly processed by a lathe. However, for some workpieces with larger specifications, due to their excessive length, they will exceed the processing range of the lathe equipment. Therefore, after the workpiece is longitudinally symmetrically cut open, milling groove processing is carried out by a milling machine. In the subsequent processing procedures of the cut-open workpiece, due to the gap loss during cutting, the combined workpiece is not a complete circle after combination, and it is necessary to re-turn the outside of the bushing by a lathe after re-combination to re-round the outside of the bushing. The existing three-jaw chucks cannot stably clamp two semi-circular workpieces. Therefore, a fixing hoop for stably combining two semi-circles is needed. Summary of the Utility Model
[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art, and provide a fixing hoop for combined processing of semi-circular workpieces, which solves the above problems.
[0005] To achieve the above purpose, a fixing hoop for combined processing of semi-circular workpieces is provided, which includes a first half-hoop, a second half-hoop, and two fixing screws. Both the first half-hoop and the second half-hoop are semi-circular hoop bodies. Threaded holes are respectively opened at the centers of the two ends of the first half-hoop. Right-angle grooves are respectively opened on the outer sides of the two ends of the second half-hoop. Bolt through-holes are respectively opened in the middle parts below the two right-angle grooves. The positions of the two bolt through-holes are respectively located at the centers of the two ends of the second half-hoop. The two ends of the first half-hoop and the second half-hoop are fixedly connected through corresponding fixing screws. Arc-shaped grooves are respectively opened in the middle parts of the side walls of the two right-angle grooves. The centers of the cross-sections of the two arc-shaped grooves respectively coincide with the centers of the corresponding bolt through-holes.
[0006] According to the fixing hoop for combined processing of semi-circular workpieces, the two fixing screws respectively pass through the bolt through-holes and are threadedly connected with the corresponding threaded holes.
[0007] According to the fixing hoop for combined machining of semi-circular workpieces described above, both of the two fixing screws are hexagon socket head cap screws, and the radian of both of the two arc-shaped grooves corresponds to the radian of the nut of the fixing screw.
[0008] According to the fixing hoop for combined machining of semi-circular workpieces described above, the lateral groove depth of the two right-angle grooves is two-thirds of the thickness of the second semi-hoop.
[0009] According to the fixing hoop for combined machining of semi-circular workpieces described above, the two ends of both the first semi-hoop and the second semi-hoop are flat mouths.
[0010] According to the fixing hoop for combined machining of semi-circular workpieces described above, V-shaped grooves are provided at both ends of the first semi-hoop, and V-shaped angles corresponding to the V-shaped grooves are provided at both ends of the second semi-hoop.
[0011] The above solution has at least one of the following beneficial effects:
[0012] 1. The utility model is provided with a first semi-hoop and a second semi-hoop. In cooperation with two fixing screws, after two semi-circular workpieces are closed, the two fixing screws can be tightened. Through the fastening method of the two semi-hoops, stable combination can be carried out. During production, the design of the right-angle groove of the second semi-hoop is more convenient for processing and the screw connection is more stable compared with the method of setting flanges at both ends of the two semi-hoops, which enhances the practicability of the device.
[0013] 2. By respectively arranging V-shaped grooves and V-shaped angles at the two ends of the two semi-hoops, when combining and fixing the semi-circular workpieces, only need to place the first semi-hoop under the semi-circular workpiece first, then when installing the second semi-hoop, through the radian of the semi-circular workpiece itself and the cooperation of the V-shaped groove and the V-shaped angle, the first semi-hoop and the second semi-hoop can be self-positioned. The staff only needs to place the second semi-hoop and then directly tighten the fixing screws, which improves the operation simplicity and enhances the practicability of the device.
